The relationship between the BCzout and input-output approaches to right-coprimeness is investigated. We introduce a generalized BCzout identity and analyze its relationship to right-coprimeness. In terms of the generalized BCzout identity, a right factorization of a nonlinear plant is coprime acco

โฆ Synopsis
In this paper, algorithms for the computation of all matrices of the generalized polynomial Bezout identity are proposed. The algorithms are based on the computation of minimal polynomial basis for the right null spaces of certain polynomial matrices. For this reason, an algorithm for the computation of minimal polynomial bases is also proposed. Since this algorithm relies solely on singular value decompositions of certain real matrices, formed with the coefficients of the polynomial matrix whose minimal polynomial bases one is interested in finding, it can be said to be robust.

In this paper, we examine the effect of dissecting an n-dimensional simplex using cevians (cross-sections passing through n&1 of the vertices of the simplex). We describe a formula for the number of pieces the simplex is dissected into using a polynomial involving only the number of each type of cev
